[SysAdmin] GitReloadAPIView:: Couldn't entertain reload request for the branch (master), expected branch is ...

[sentry-io]

We're getting this error a lot, but I don't think it should return a 400. Since github fires a webhook for every commit, we will necessarily receive webhooks that are for a branch other than the configured one.

Instead of a 400, we should return a 200 response with a message about how no action was taken.
